LOS ANGELES (AP) — Rachel Reilly doesn't have a reason to pout.

After being locked away from the outside world for 75 days, the weepy "Big Brother" veteran emerged Wednesday as the winner of CBS' voyeuristic reality TV competition. The show's six-person jury selected the 26-year-old cocktail waitress from Los Angeles to win the $500,000 grand prize over 23-year-old newbie contestant Porsche Briggs from Miami.

At the beginning of the 13th season, Reilly entered the "Big Brother" house with fiance Brendon Villegas, a 31-year-old graduate student. The pair met last summer as competitors on the show's 12th edition. The ups and downs of their relationship and the game often resulted in emotional outbursts from Reilly.

Reilly dominated the season by winning competitions with her veteran alliance and openly targeting the batch of fresh players.
